Abstract

Вулканізовану гуму піддають девулканізації шляхом контактування вулканізованої гуми з рідким скипидаром у реакційній суміші за відсутності лужного металу.Vulcanized rubber is subjected to de-vulcanization by contacting vulcanized rubber with liquid turpentine in the reaction mixture in the absence of alkali metal.
